Many years ago, a friend of ours had a heat pump and the utility company HAD to buy any excess.
No matter what, utility companies are a monopoly. They sure don't want folks to start putting windmills into apartment complexes or commercial ventures.
We have something REALLY stupid here....a big great grant for a roof garden....The money is in the bank. But they can't find a roof that will support the load....AND IT HAS TO BE MAINTAINED. All to save 2 cents.
Stupid....just stupid
Good luck with the whole roof garden thing.
It’s not just the load. If the roof isn’t properly designed and built from the beginning for such use, installing one is generally a disaster.
